| | | | | | | New convention: compare 'with' for asymmetric comparisons (greater or lesser than), and compare 'and' for symmetric comparisons. Worth making this distinction even though the opcodes are identical; when we compare 'with', the order of operands is significant.

* 4981 - no, go back to 3 phasesKartik Agaram2019-02-181-1/+1
| | | | | | | | | | | | | Considering how much trouble a merge phase would be (commit 4978), it seems simpler to just add the extra syntax for controlling the entry point of the generated ELF binary. But I wouldn't have noticed this if I hadn't taken the time to write out the commit messages of 4976 and 4978. Even if we happened to already have linked list primitives built, this may still be a good idea considering that I'm saving quite a lot of code in duplicated entrypoints.

| | | | | Support immediate operands in the data segment in all the ways we support them in the code segment.

| | | | We only can't use rm32=5 when mod=0. Totally fine when it's mod=1.

| | | | | | | | | | | | | | | | Some automated commenting cleanup.

| | | | | Standardize on hyphens in all names. And we'll use colons for namespacing labels in functions.

| | | | | | | | Start requiring a '-o' flag to designate the output binary when translating. Things currently get funky if you pass in multiple inputs, but that's ok. This is the first step to supporting multiple input files for a single output binary.

| | | | | | | More calling convention tweaks. Use EBP to get consistently at parameters and locals. Always put the first function argument closest to EBP.

New helper: compare a null-terminated string (from argv) with a length-prefixed string (anywhere else). As long as ex11 continues to pass we can copy the function and its tests to other programs.
